Letters Patent No. 65,613, dated June 11,1867

IMPROVED BRICK MACHINE.

Be it known that I, HENRY C. SERGEANT, of Columbus, in the county of Franklin, and State of Ohio, have invented a new and useful improvement on what is known as the Guard Brick Machine; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation'of the same, 'reference being had to the annexed drawings, making a part of this specification, in which- Figure 1, a plan view.

Figure 2, a partial section of the mould-wheel. f

Figure 3, a side elevation of the weight lever and fulcrum for finishing the upper side of the brick.

Figure 4 showing the inclined tracks attached to the periphery of the mouldwheel, also .the arm with inclined end and toe for working on the track, raising and' dropping the weight on to each brick whilst in the mould.

Figure 5 is a section of the wheel for cleaning the face of the mould-wheel and working the stones down into themoulds..

Letters A A A are intended to represent the frame, constructed of wood or any suitable material. B represents the mould-wheel. C C 'show the bottom of the tub with a recess or opening at the bottom for the admission of the clay, which is mixed and pressed down into the moulds in the ordinary way. D represents a wheel, which can be made of a section and not revolve,'or whole, and revolve or not. The edge is bevelled oif, as shown'in iig. 5, with a space on the lower side for the clay to Work up into and relieve the strain, and then be scrapedoii` again by. the square projection depositing the mud alongside of the mould-wheel, which can be cleaned by a stationary scraper when the scaper D is made to revolve. Letters E represent a weight, which in a. large machine will weigh about one hundred and fifty pounds, which is raised up bymeans of the arm -F and the inclined tracks gg, shown in figs. 1 and 4, and is let fall at the end of each track., The pin i, shown in iig. 3, dropping into the holes shown atj in tig. 1, which holds the weight' into its proper place until the wheel has travelled far enough to raise the pin entirely out of the hole, then its gravity will bring it back to the notch on arm F, shown in g. 4, sliding down the incline on the end of the arm, which is increased by the raising of the arm on the inclined track. Letter K, in fig. 3, shows the collar, which plays loose upon the shaft of the mould-wheel, and carries the pin or fulcrum for the arm which the weight is attached to, guiding the weight whilst moving in a circle. A light spiral spring can be attached to the end of the lever for bringing it buck to its position, if found necessary. Letter t in fig; 2 shows the `i`ol1ower with one round stem orguide which has a bearingturned upon it for governing the thickness by slipping on thestem one or more'washers. Screws have been used, but they become rusty and not manageable. 4 4 l y Having fully shown and described the working of the-parts, I willl proceed to state what I claim as new, and desire to secure by Letters Patent;` I l 1. I claim th'e weight E with its arm when made to hinge and turn upon the shaft of the mould-wheel, for the purpose specified. I

2. I claim the inclined tracks when attached to the periphery of the mould-wheel for raising and dropping a weight upon the face of the brick ibnnishing as shown and described. l

3. I claim the arm, toe, and inciine on the end of arm for facilitating the-raising and getting the Weight back to its place. 1 i

4. I claim the stop z' attached to the arm' or-weight E, whenoperated to drop into holes or notches for the purpose of preventing the weight from sliding on the brick when, being raised up, as shown and described.
